Definitions
- the solid bed can be converted by gas supply against gravity in the fluidized bed state.
- the fluidized bed behaves then similar to a liquid and can leak through outlet openings, side nozzles, etc.
- the disadvantage is that large amounts of gas are needed. To make matters worse, that very fine particles can be very difficult to convert into a homogeneous vortex layer.
- Another way to enable the solids discharge from a container is to provide, taking into account the bulk material properties conical outlet geometries.
- the solids discharge from a cone out can be supported by adding gas via lances (US 5 129 766) or to the cone walls (CH 209 788).
- the amount of gas is usually less than the amount that would be required for fluidization, but sufficient to cancel the wall friction of the bulk material and / or to prevent local approaches to bridge formation.
- An air-permeable intermediate floor with elastic, self-closing valve nozzles is shown in DE 11 70 988.
- the prior art is to supply via porous elements gas in the outlet cone (US 2006/0013660 Al, US 4,941,779).
- the porous elements are preferably made of sintered metal, but may also consist of other porous media.
- the use of porous materials has some procedural and operational disadvantages: The permissible pore size is based on the solid to be handled or on its particle size distribution. The pore size can only be reduced to a reasonable level, which results from the desired retained particle size and fürstömungstikutzes. In practice, it can be stated that even with very small pore sizes, the porous medium becomes clogged over time. The reason for this is that the finely ground fuel to be handled has a particle size distribution in which even the finest particles are present, which can settle in the pores.
- porous materials may only be charged with particle-free gas. It is not possible, e.g. to use gas generated from container depressions and particle-contaminated gas, since the porous materials would clog up from the gas feed side.
- the object of the invention is, in particular the use of porous materials, such as sintered metals od. Like. to avoid providing good conveying properties in the transfer funnel without limiting the grain sizes of the respective material, with particle-laden gas can be used for the promotion.
- gas outlet openings are provided with a projecting into the interior of the annular space, at least one angle with an imaginary horizontal plane having gas supply channel and
- the introduction of the gas required for conveying into the annulus means the possibility of optimal homogenization of the gas distribution, a resuspension of the gas distribution and the gas u. like. more.
- the gas supply channel is part of a retaining element for preventing the Einrieseins of solid in the annulus.
- the retaining element may be provided on a single gas supply channel or may be equipped with a plurality of gas supply channels.
- annular space-side effective end of the gas supply channel in the direction of gravity above or below the outlet opening of the gas supply channel is in the hopper, which in particular substantially prevents solids from passing through the openings in the funnel wall to the outside, in particular in the Annular space for gas supply.
- each retaining element is provided with gas distribution openings or gas inlet openings situated in the direction of gravity above the gas outlet openings.
- the retaining elements can be designed annular or cross-sectionally angular.
- the Ring space is equipped at least with a double bottom to form a lower part of the annular space in the direction of gravity is equipped with at least one gas supply and one or a plurality of gas outlet nozzles on the inner annular space floor.
- annular space is divided by a plurality of floors in annulus segments, each segment is assigned at least one distributed over the circumference plurality of gas outlet openings and at least one gas supply.
- gas supply is made via ring lines at the bottom of the respective annular space.
- gas supply slots instead of approximately circular gas outlet openings provided, these slots may be similar to the gas outlet openings arranged in horizontal rows on the handling of the funnel, possibly offset from each other, the slot design can be provided so that, for example the slot forms an exit angle to the horizontal against the force of gravity or in the direction of the force of gravity, subliminal slot configurations being possible with different media to be conveyed.
- the invention also provides a method using a device with the preamble feature of claim 1, characterized in that it is acted upon by a gas supply of the effective bottom space of the annulus formed by the double-walled funnel so that in the annulus a possibly located there solids fugitive dust forms billowing flow, wherein via gas outlet openings with angular gas supply channels, the fluidized gas is injected into the inner funnel at an angle to the direction of gravity.
- cones can be arranged on a container. Furthermore, it may have manufacturing advantages to provide several cones possibly different size in series.
- FIG. 1 shows a partial cross section through a discharge cone of a non-illustrated solid containing container
- Fig. 2 shows a further modified embodiment of the Austragskonusses and in the
- the discharge cone 1 shown in Fig. 1 is designed double-walled.
- gas is supplied in the annular space 6, which is located between the inner wall 7, outer wall 5, intermediate bottom 9 and upper flange.
- Gas is first introduced into the underfloor space 10 via a gas feed connection and line 8.
- leads which is located between the inner wall 7, outer wall 5, intermediate bottom 9 and lower flange.
- the gas is distributed from there via nozzles 11 located in the intermediate bottom 9 into the annular space 6.
- the nozzles 11 are aligned parallel to the intermediate bottom 9 and employed tangentially, so that adjusts a swirling gas flow in the annular space 6.
- the underbody space 10 serves to distribute the gas to the nozzles 11, wherein the intermediate bottom 9 simultaneously provides a flat surface from which deposited dust particles can be removed by the gas flow.
- FIG. 1 with intermediate bottom 9, nozzles 11 and bottom space 10 is particularly advantageous when it comes to bulk material with larger particle diameters, which require a high speed and as undisturbed flow to raise from the ground.
- structurally simple variants of the gas supply can be used in the annular space, which are shown in Figs. Ia and Ib.
- Fig. Ia the gas supply takes place directly over the gas supply nozzle 8, at the end in the annular space 6, a Umlenkdüse 15 is provided to give the incoming gas a tangential orientation, wherein a gas supply nozzle 8 may be provided with Umlenkdüse multiple.
- Fig. Ib A further variant of the gas supply is shown in Fig. Ib, in which via the gas supply port 8 gas a ring line 16 is fed, which is located in the annular space 6. From the ring line 16, the gas is injected via nozzles 17 in a preferably tangential direction in the annular space 6.
- From- Direction of the nozzles 11,15,17 preferably takes place tangentially and horizontally (with respect to the gravitational field), but may also be directed in deviating from the tangent up to 45 ° in the radial direction and / or up to 45 ° from the horizontal upwards.
- the gas supply openings 4 with their gas supply channels 4a according to the invention are designed so that they are considerably larger than the largest particle diameter of the solid, for example at least three times larger than the largest particle diameter.
- the gas supply openings 4 are provided in the annular space 6 with a retaining device 12, which has the task of retaining backflowing solid.
- the restraint device may therefore consist of an easy-to-manufacture ring which is turned off at an angle so that it has surface contact with the conical inner wall 7.
- the annular design also has the advantage that an outer surface can be turned off at any angle to the vertical, so that in a simple manner any angled holes can be performed simultaneously by retaining device 12 and inner wall 7.
- the gas supply opening 4 can be designed with arbitrary angles of attack on a very simple production technology, whereby the retention of the solid is favored (see, for example, detail in FIG. 1).
- the annular design of the retaining device 12 makes it possible to install a larger number of holes on the circumference and to provide holes in several rings over the height on several levels, in FIGS. 1 and 2, three levels for gas supply openings 4 are exemplified.
- the annular restraints 12 also reinforce the conical inner wall 7.
- Another possibility of the design is outlined in FIG.
- the gas supply openings 4 are here for example designed as slots, which may also be angled to the horizontal, as the holes (see sections a to c in Fig. 2).
- the retaining device 12 is here alternatively mounted, for example, as an angled plate behind the gas supply openings 4.
- a gas distributor device 13 which covers the side of the retaining device 12 facing the annular space 6.
- the gas distributor device 13 is itself provided with gas inlet openings.
- the main task of the gas distributor device 13 during operation is to accomplish the gas distribution to the gas supply openings associated with the individual restraint devices.
- the pressure loss of each gas distributor device 13 can be adjusted by a suitable choice of the inflow opening 14.
- a uniform distribution to all gas supply openings can be achieved or targeted the gas supply to each restraint device can be adjusted with the associated gas supply openings. This can be done in a simple way e.g. the different pressure conditions, which result from different heights of the gas supply openings in the cone, be taken into account.
